Doppler and echocardiographic features of normal and dysfunctioning bioprosthetic valves.
Alam M, Rosman HS, Lakier JB, Kemp S, Khaja F, Hautamaki K, Magilligan DJ Jr, Stein PD. Alam M, et al. J Am Coll Cardiol. 1987 Oct;10(4):851-8. doi: 10.1016/s0735-1097(87)80280-2. J Am Coll Cardiol. 1987. PMID: 3309005 Free article.
Although the Doppler regurgitant jet was peripheral in seven of the nine patients with paravalvular regurgitation, it was not possible to differentiate these patients from those who had valve degeneration and cusp tear at the periphery of the valve ring. Eight patie …

Leaflet tear in a Trifecta aortic bioprosthesis 34 months after implantation.
Piñón M, Durán D, Pazos P, Pradas G. Piñón M, et al. Interact Cardiovasc Thorac Surg. 2015 Feb;20(2):281-2. doi: 10.1093/icvts/ivu384. Epub 2014 Nov 16. Interact Cardiovasc Thorac Surg. 2015. PMID: 25404230
Bovine pericardial valves have excellent haemodynamics and equivalent freedom from reoperation compared with a porcine bioprosthesis [ 1]. However, early failure (parastent post-cusp tear) can take place due to mechanical stress. We report an acute structural failur …

Applications of pulsed Doppler flow mapping to left sided cardiac valvular lesions.
Kalmanson D, Veyrat C, Gourtchiglouian C, Bas S, Abitbol G. Kalmanson D, et al. Int J Card Imaging. 1986-1987;2(1):37-45. doi: 10.1007/BF01553935. Int J Card Imaging. 1986. PMID: 2959728
For example, using this technique, it is now possible to easily differentiate a cusp tear from a leak of a bioprosthesis, to measure the size of the leaks, and to reconstruct the image of aortic or mitral stenotic areas. ...

Long-term echocardiographic follow-up of patients with a tricuspid bioprosthesis.
Okada Y, Nasu M, Nishiuchi S, Shomura T. Okada Y, et al. ASAIO Trans. 1990 Jul-Sep;36(3):M535-7. ASAIO Trans. 1990. PMID: 2252744
Color Doppler showed regurgitation in 7 of the 20 patients who were completely followed up, but they were all asymptomatic and required no special intervention. Cusp tear or calcification requiring reoperation was not observed in this study, including 8 patients you …

Traumatic sinus of Valsalva fistula and aortic valve rupture.
Murray EG, Minami K, Körtke H, Seggewiss H, Körfer R. Murray EG, et al. Ann Thorac Surg. 1993 Mar;55(3):760-1. doi: 10.1016/0003-4975(93)90290-x. Ann Thorac Surg. 1993. PMID: 8452445
The trauma occurred 2 1/2 years previously. The fistula was closed with a Dacron patch, and the cusp tear was sutured....

Aortic regurgitation due to perforation of the right coronary cusp 10 years after implantation of a freestyle stentless bioprosthesis.
Okamoto Y, Katsu M, Matsumoto M. Okamoto Y, et al. J Card Surg. 2011 Nov;26(6):613-4. doi: 10.1111/j.1540-8191.2011.01303.x. Epub 2011 Sep 26. J Card Surg. 2011. PMID: 21951139
Valve deterioration following aortic valve replacement using the Freestyle stentless bioprosthesis is related to cusp tear, operative injury, or infection. We report a patient with aortic regurgitation due to perforation of the right coronary cusp 10 years after imp …
